Answer:
360-degree appraisal
Step-by-step explanation:
A type of performance appraisal where a particular employee is assessed by same-level colleagues, managers and subordinates is called a 360-degree appraisal. This is one of the most effective types of performance appraisals, as it includes constructive feedback from various perspectives - which are relevant for proper and thorough assessment.
Sometimes, feedback and appraisal just from one employee type (manager or subordinate) is not relevant and complete. Then, a 360-degree appraisal is a great choice.
